Hi George
I've cleaned up your code a bit, I think some of the commands for
freeing things were in the wrong place. They should only be called if
you are successful in getting them, apart from CloseDevice which
according to the autodocs should always be done to match with
opendevice. Hmm, don't know if thats right though. Apart from that it
all looks fine. Don't have the docs to check the way you've used the
library though.
The real problem is probably in the IOStdReq newtype. I'm sure there
are unions in it that hasn't been converted properly in the latest
version of amigalibs.res, so the size will be wrong. James Boyd has a
fixed version, or its in one of his archives on Aminet (for playing
aroung setting the mouse position).
; amigalibs.res is resident
INCLUDE "cdplayer.h.bb2" ;contains some structures,changed to blitz
format
